Embodiment 1

[0166] An embodiment of the present invention provides a method for service chaining, which is used in a service chain-enabled domain network (ServiceChain-enabled Domain Network).

[0167] Such as figure 1 As shown in , it is a schematic diagram of the architecture of the service chain enabling domain network. One or more service chain policy decision points and multiple service nodes (SNs) for providing value-added services are usually deployed in the service chain enabling domain network. A flow classifier may also be deployed in the service chain enabling domain network.

[0168] Among them, SN is used to provide one or a group of specific value-added services, such as firewall (FireWall), deep packet inspection (Deep Packet inspection, DPI), etc., corresponding to value-added service modules; at the same time, it is necessary to support BGP (BorderGateway Protocol, Border Gateway Protocol ) and basic routing addressing and forwarding functions, corresponding to the basi...

Embodiment 2

[0192] Such as Figure 4 As shown, the embodiment of the present invention provides another method for service linking, which is used in the service chain enabling domain network, and the service chain policy decision point is deployed in the service chain enabling domain network, which is used to provide value-added service service nodes SN, the SN includes an ingress SN, an intermediate SN, and an egress SN, and a service chain path from the ingress SN, through the intermediate SN, to the egress SN programmed by the service chain policy decision point, the Methods include:

[0193] 401. The intermediate SN receives an extended first Border Gateway Protocol BGP message sent by a downstream SN directly adjacent to the intermediate SN on the service chain path, and the extended first BGP message includes the A service chain path identifier and the first service chain path, the service chain path identifier is used to identify the service chain path, and the first service chain...

Embodiment 3

[0215] Based on the technical solutions of Embodiments 1 and 2, this embodiment also provides a method for service linking. The method of this embodiment takes the entry SN of the service chain as the execution subject.

[0216] The method in this embodiment is used in a service chain enabling domain network, where a service chain policy decision point is deployed to provide a service node SN for value-added services, and the SN includes an ingress SN and an egress SN, and a service chain path from the ingress SN to the egress SN programmed by the service chain policy decision point.

[0217] Please refer to Figure 5 , the method of this embodiment may include:

[0218] 501. The ingress SN receives an extended BGP message sent by a downstream SN directly adjacent to the ingress SN on the service chain path, and the extended BGP message includes a service chain path identifier and a first service chain a path, the service chain path identifier is used to identify the service...

Abstract

A service chaining method, device and system to provide an easy-to-deploy service chaining solution. In some embodiments of the present invention, the method includes: the intermediate SN receives the extended first Border Gateway Protocol BGP message sent by the downstream SN directly adjacent to the intermediate SN on the service chain path, and the extended first BGP message includes The service chain path identifier and the first service chain path, the service chain path identifier is used to identify the service chain path, the first service chain path is a path including the service chain path from the entrance SN to the intermediate SN; the intermediate SN is determined to be in the first service chain path On the chain path, the upstream SN directly adjacent to the intermediate SN; the intermediate SN sends the extended second BGP message to the upstream SN; the extended second BGP message includes the service chain path identifier and the second service chain path, and the second A service chain path is a path including a service chain path from an ingress SN to an upstream SN.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for realizing service linking. Background technique [0002] In the fields of mobile, fixed broadband and data center applications, there is a requirement for a specific user's specific application business flow to be concatenated with multiple value-added business services in sequence. For example, in mobile or fixed broadband applications, for Http (Hypertext transfer protocol, hypertext transfer protocol) or Web (web page) online business flow, it is necessary to sequentially connect three value-added business services of content filtering, caching service and firewall before entering the Internet (Internet, Internet); for video service streams, there is no need to pass through content filtering, and two value-added service services, caching service and firewall, can be connected in sequence; while encrypted service streams only need ...
